This is a game changer for frizzy hair OMG! This is a great shampoo for frizzy hair!I’ve purchased many expensive shampoo brands and none worked until this.I highly recommend this and encourage anyone with frizz to try this. I’m in the Florida humidity and this works wonders.
Smooth Yet Light I used it this morning for the first time. I love it. I didn't even use conditioner, and I have long hair. I hope to buy the conditioner someday, but there's no hurry! Like the title says, "Smooth Yet Light".
Love it Great
I would recommend This is a good product for a reasonable price.
Smoothes and repairs, shiny and natural, great scent Smoothes and repairs. Saved my hair. Great for delicate, humidity-prone hair. Smoothe and fresh every time and smells wonderful.
Great Shampoo Finally recieved my order after the 1st shipment was lost/delivered to the wrong address. Absolutely love this shampoo and conditioner. Just in one use my hair feels and looks great. A little pricey but well worth the cost. Lathers great and you don't need to use much. This will be my only shampoo and conditioner from now on.
WHAT A DIFFERENCE! Biolage Smooth Proof Shampoo is fantastic! It leaves my hair feeling incredibly soft, smooth, and manageable without weighing it down. I’ve noticed a big difference in frizz control, even in humid weather, and my hair looks healthier and shinier after each wash. The scent is light and refreshing, and a little goes a long way. This has become a staple in my hair care routine and I highly recommend it for anyone looking for smooth, polished hair.
Best shampoo This is my favorite shampoo; it gets all the gunk out of my hair. After, my hair feels so clean. It makes my hair smell good.
